Mercury is a terrestrial planet. Mercury is the first planet from the sun. Its takes Mercury 59 days to make one rotation and 88 earth days to make one revolution. Mercury has 0 moons and its mass is 5.5% compared to earth. Mercury's average distance from the sun is about 46,001,200 km.
In diameter Mercury is about 4,879.4 km.
Mercury is a rocky planet and it has many many craters. Because Mercury is so close to the sun it can switch back and forth from hot to cold and cold to hot. When the planet is hot it can get up to 430 degrees celcius, and when it is cold and can become -180 degrees celcius there might also be ice on it but nobody knows for sure. NASA is sending a spacecraft to Mercury and if it goes well the the spacecraft will go into orbit around Mercury. URANUS Uranus is 2,870,186km away from the sun. It takes Uranus 17 hours and 14 minutes to make one rotation and it takes Uranus 30,799 days to make one revolution.Uranus is a very cold planet and appears to be green. Mercury has helium, hydrgeon, and methain that makes it mushy on the surface.The planet is also the third biggest planet but only in diameter.It takes Uranus at least 84 years to circle around the sun.
Interesting Facts Uranus was the first planet to be seen by telescope. Uranus has only been visited by one spacecraft called the Voyager 2 on January 24 1986. Uranus is the father of Cronus (Saturn).
THE SUN The sun appears larger than any other star because it is the closest to Earth. The sun is the largest object in the solar system. The sun's temperature in its core is 15,600,000km. The sun is about 4.5 billion years old and eventually will die out. The sun is 1 million times the size of Earth.
Red hot burning sun.
STARS
A star starts off as a cloud of gas and dust called stellar nursery's. What happens to a star after its main sequence depends on its mass. White dwarf stars are aslo called dead stars. The stars that you see at night are called Binary stars. Stars shine bright at night because of the amount of energy inside of them.
